BACKGROUND OF THE PRESENT INVENTION Field of Invention

The present invention relates to an optical imaging device, and more particularly to an iris recognition device, a manufacturing method therefor, and an application thereof.

Description of Related Arts

With the development of the Internet and its applications, identification technology and authentication methods have great significance for the user's information security.

The traditional identification technology is based on the development of touch technology and identifies the user's identity by a sensor sensing touching or pressing. However, the required software and logic which are in response to and perform the process of touching and pressing are complex, so that the system matching user information costs a longer time, and the accuracy of the matching results is not effectively guaranteed. In other words, the recognition technology based on the touch technology may has a wrong matching result, as a result, it not only brings unnecessary trouble to the user, but also is a threat to the user's information security.

Iris recognition technology is a bio identification technology. Iris is one of the most stable human biological characteristics and has unique characteristics s, which provides basic conditions for the development and wide application of iris recognition technology. When using iris recognition technology for user authentication, users do not need access to the sensor. Compared with the traditional identification technologies based on the development of touch technology, iris recognition technology has a greater reliability in the aspect of user authentication results.

However, the traditional iris recognition technology also has many problems to limit performances. On one hand, the traditional iris recognition technology has a low image quality to collect a user's iris characteristics, and can only be collected at a close range. Once the distance is relatively far, it cannot accurately capture the iris characteristics of the user, therefore, the practical value of the traditional iris recognition technology is not high.

On the other hand, the traditional use of iris recognition technology use monocular (left or right) iris characteristics s for processing, and the positioning and environmental requirements of shooting subject eyes are very high, resulting in the traditional iris recognition technology having more restrictive conditions of collecting users iris characteristics s, and resulting in not convenience enough to shoot users. More importantly, the collected monocular iris characteristics information by the traditional iris recognition technology is insufficient, which further limits the development of the traditional iris recognition technology.

It is worth mentioning that the iris recognition device 100 can be applied in a variety of external systems. In some embodiments of the present invention, the external systems comprise but not limited to safety devices such as safety box, smart devices such as mobile electronic devices, personal digital assistants, personal computers, and application programs such as online payment procedures.

The iris recognition device 100 is further communicatively connected with a background processing component 200, in such a manner that the iris recognition device 100 acquires the user corresponding characteristics and transmits the user corresponding characteristics to the background processing component 200 to be processed such as analysis, calculation, matching and so on. The iris recognition device 100 collecting user iris characteristics can be combined with other recognition devices to collect biometric characteristics such as facial characteristics, fingerprint characteristics, voice characteristics and so on so as to follow-up identify the user's identity, thereby ensuring user information security.

Referring to FIG. 1 and FIG. 2 of the drawings according to an embodiment of the present invention, the background processing component 200 is implemented as a microprocessor, and during manufacturing of the iris recognition device 100, the background processing component 200 is mounted on the printed circuit board 30 such that the iris characteristics collected by the iris camera module 10 is quickly and efficiently transferred to the background processing component 200 to be processed. In the embodiment, the iris recognition device 100 has a high degree of integration to save assembly cost when an external system is assembled.

Referring to FIG. 3A of the drawings, another embodiment of the present invention is illustrated. The iris recognition device 100 is provided with a data interface 101 in advance. The background processing component 200 has a connection end 201 which is coupled with the data interface 101 to communicatively connect the iris recognition device 100 with the background processing component 200, thereby enabling data transmission between the iris recognition device 100 and the background processing component 200.

Referring to FIG. 3B of the drawings, another embodiment of the present invention is illustrated. The iris recognition device 100 and background processing component 200 are communicatively connected by a wireless connection in such a manner that the iris recognition device 100 is ensured to have a flexibility on specific application.

It is worth mentioning that the wireless connection between the iris recognition device 100 and the background processing component 200 comprises but not be restricted to Wi-Fi, Li-Fi, internet, communications networks and Bluetooth.

In other words, the iris recognition device 100 and the background processing component 200 are communicatively connected by a wired connection or a wireless connection such that iris recognition device 100 meets different using requirements.

As shown in FIG. 4A and FIG. 4B of the drawings, different amount of the fill light component 20 is provided in different embodiment of the present invention and the position of each of the fill light component 20 can be adjusted. For example, the amount of the fill light component 20 can be one and the fill light component 20 is provided on the corresponding position of the iris camera module 10 to provide supplementary light source when the iris camera module 10 collects the users iris characteristics, so that the quality of the user iris characteristics images is relatively higher; the amount of the fill light component 20 can be two and the two fill light component 20 are symmetrically provided on the corresponding position of the iris camera module 10 to provide supplementary light source when the iris camera module 10 collects the user iris characteristics. In another embodiment of the present invention, the amount of the fill light component 20 can also be more, and each of the fill light component 20 is surround provided in the iris camera module 10, the present invention is not limited in this aspect.

It is worth mentioning that the amount and position of the fill light component 20 described above is exemplary and preferable only and not intended to be limiting.

In other words, in order to improve the reliability of the iris camera module 10 in the user iris characteristics collection, the fill light component 20 provides supplementary light source from at least one orientation of the iris camera module 10, so that when the iris camera module 10 is used to collect the user iris characteristics, the user reflective spot is reduced or the generated user reflective spot is located outside of the iris such as the sclera region.

It is worth mentioning that when the iris camera module 10 collects the user iris characteristics, the shooting method is infrared light black and white photography, as the user is in general environment which has not enough infrared light to support this shooting process, so that high quality of user iris characteristics image is acquired by the fill light component 20 providing additional light source.

Thus, the light source provided by the fill light component 20 is LED infrared light source to meet the shooting needs of the iris camera module 10. The fill light component 20 supplements infrared lights for user binoculus region when the iris camera module 10 collects the user iris characteristics. Wherein the iris camera module 10 is preferably an infrared camera module, so that when the iris camera module 10 collects the user iris characteristics, the interference of the external visible light is avoided as much as possible. Furthermore, the use of the fill light component 20 will not make user binoculus region to feel discomfort, so that when the iris camera module 10 shoots the user binoculus region to acquire images, a uniform brightness is formed in user's iris region. Moreover, not only the accuracy of the user iris characteristics acquisition is improved by the infrared light, but also the efficiency and reliability of the iris recognition device 100 processing user authentication are enhanced.

In this preferred embodiment of the present invention, the fill light component 20 comprises a light emitting element 21, wherein the light emitting element 21 preferably is an infrared LED light-emitting element to ensure that under the condition of the fill light component 20 providing enough additional infrared light for the user iris characteristics collection of the iris camera module 10, the energy consumption of the iris recognition device 100 is reduced and damage caused to the user's eyes is avoided.

As shown in FIG. 5 of the drawings, during the user iris characteristics collecting process by the iris recognition device 100, the iris camera module 10 covering the face region of the user is defined as an interior region, so that the when the iris camera module 10 collects the user iris characteristics, the focal point is substantially in the user's iris region and preferably the focal point is located in the pupil region; accordingly, the fill light component 20 covering outside of the user's face region is defined as an exterior region, so that the user face region covered by the fill light component 20 always comprises the user face region covered by the iris camera module 10 and at least one eye of the user is located in the interior region. In such a manner that the fill light component 20 provides additional infrared light source for the iris camera module 10 in any cases.

It is understandable that the light emitting element 21 of the fill light component 20 has a light emitting angle which is set to be less than 90 degrees, so that the supplemental infrared light source provided by the fill light component 20 is effectively utilized. It is worth mentioning that the light emitting angle of the light emitting element 21 of the fill light component 20 is set to be less than 45 degree, so that under the condition of ensuring that enough supplementary infrared light is provided for the iris camera module 10 by the fill light component 20, the energy depletion of the iris recognition device 100 is reduced.

Those skilled in the art will understand that the light emission intensity of the light emitting element 21 of the fill light component 20 is changed with the light emitting angle. As shown in FIG. 6 of the drawings, with the increasing of the light emitting angle of the light emitting element 21, the light emission intensity of the light emitting element 21 becomes smaller, and the light emission intensity of the light emitting element 21 and the light emitting angle has a function change. It is understandable that, according to test results of the light emission intensity of the light emitting element 21 and the light emitting angle, when the light emitting angle of the light emitting element 21 is at an angle between 0 degree and 45 degree, the luminous intensity of the light emitting element 21 changes gently; when the light emitting angle of the light emitting element 21 is at an angle between 45 degree and 90 degree, the light emission intensity of the light emitting element 21 has a rapid change.

As shown in FIG. 6 of the drawings, under an ideal condition, when the light emitting angle of the light emitting element 21 is 0 degree, the light emitting element 21 has the maximum light emission intensity and the depletion energy of the light emitting element 21 is the least. In a specific application of the invention, the iris camera module 10 and the fill light component 20 has a predetermined distance. In order to make the fill light component 20 and the iris camera module 10 to simultaneously act on a same object such as the user iris region, the fill light component 20 and the iris camera module 10 has an angle. According to the test result of the iris recognition device 100, when the light emitting angle of the light emitting element 21 is less than 45 degree, the depletion energy of the light emitting element 21 is the least, and each of the fill light component 20 and the iris camera module 10 has an optimal configuration state.

As shown in FIG. 7 of the drawings, a distance between the iris camera module 10 and the user iris is defined as z, an axle distance of the iris camera module 10 and the fill light component 20 is defined as x, an inclination angle of the fill light component 20 is defined as θ, and a formulas relationship of the z, x and θ is tan θ=z/x. Based on the formulas tan θ=z/x, a deviation value of the iris camera module 10 and the fill light component 20 is determined. Those skilled in art will understand that when z is in a determinate state, x and θ have a changing rule of the tangent function. The value of x can be determined by adjusting the value of θ or the value of θ can be determined by adjusting the value of x. In this way, the deviation value of the iris camera module 10 and the fill light component 20 can be determined.

It is worth mentioning that, when the angle θ is reasonable, the reflective spots formed on the user iris by the light emitting element 21 is reduced. Alternatively, the reflective spots is located outside of the user iris such as sclera region to avoid the generated reflective spot having interference on the image quality when the iris camera module 10 shots the user iris characteristics. As shown in FIG. 8A, FIG. 8B, FIG. 8C and FIG. 8D of the drawings, the effects of collected user iris characteristics by the iris recognition device 100 under different states are illustrated. Experiments show that supplement of the infrared light as well as the light emitting angle and the light emission intensity of the fill light component 20 enable that the reflective spots cannot interfere the user iris characteristics collection of the iris camera module 10. Therefore, in some embodiment of the present invention, the angle θ is preferably less than 45 degree. In other words, an angle between the fill light component 20 and the iris camera module 10 is preferably less than 45 degree.

Those skilled in art will understand that when the light emission intensity of the fill light component 20 cannot meet the brightness of the requirement of the iris camera module 10 collecting user iris characteristics, on one hand the brightness of the light emitting element 21 is increased and on the other hand the iris recognition device 100 can be provided with two or more than two fill light component 20.

As shown in FIG. 9A and FIG. 9B of the drawings, the brightness variation of the user iris region under different light resources is illustrated.

As shown in FIG. 9A of the drawings, under a natural light condition, when the iris camera module 10 collects the user iris characteristics, the brightness of the user iris region is substantially gradient. In this case, image quality of the user iris characteristics collected by the iris camera module 10 is poor and cannot meet user authentication requirements, thereby resulting in inefficient of the traditional iris recognition technology and being difficult to guarantee accuracy.

As shown in FIG. 9B of the drawing, after the fill light component 20 provides additional light resource for the user iris region, and when the iris camera module 10 collects the user iris characteristics, the brightness of the user iris region is more evenly, so that it is helpful to improve the quality of the user iris characteristics collected by the iris camera module 10 and the reliability of the iris recognition device 100 during using process is improved.

It is worth mentioning that the image quality of the user iris characteristics iris collected by the iris camera module 10 has an important influence on the computing speed and the logic complexity of the iris recognition device 100, and has an impact on the recognition range of the iris recognition device 100. People skilled in the art will understand that when image quality of the user iris characteristics iris collected by the iris camera module 10 is high, the complexity of the logic design of the iris recognition device 100 can be reduced, so that the consumed time of the iris recognition device 100 on user authentication is shortened.

In the preferred embodiment of the present invention, the iris recognition device 100 can achieve long-distance user iris recognition, by the miniaturization of the pixel size of the image sensor of the iris camera module 10 and the quantifiable selector mode of the crosswise pixel quantity, and combining with the design value of the lens hfov to extend the recognition distance of the iris recognition device 100, the iris recognition device 100 can be achieved the long-distance user to iris recognition by these rational design.

Specifically, the image sensor of the iris camera module 10 provides a small diameter pixel and when the iris camera module 10 collects the user iris characteristics, the number of pixels in the binoculus region is at least 10 pixels/mm and the total pixel resolution of the binoculus region is at least 1920×800 in order to meet the minimum requirements of iris recognition algorithms. Furthermore, when the iris camera module 10 collects the user iris characteristics, the resolving power of the binoculus region is at least 450 LW/PH (0.8 F).

Accordingly, as shown in FIG. 10 of the drawings, a fill light method of an iris recognition application of the present invention is illustrated, wherein the fill light method comprises the following steps.

(a) Provide an iris camera module 10 and the user's pupil is substantially focal point, and collect user iris characteristics by capturing uniform brightness from the focal point to all around.

As shown in FIG. 11A to FIG. 12 of the drawings, the iris recognition device 100 is provided with a human face camera module 40, wherein the human face camera module 40 is mounted on the printed circuit board 30 such that the iris recognition device 100 simultaneously collects the user facial and iris characteristics, so that user authentication accuracy of the iris recognition device 100 is improved by increasing information of user characteristics captured by the iris recognition device 100.

As shown in FIG. 11A of the drawings, the iris camera module 10, the human face camera module 40 and the fill light component 20 are integrated on the iris recognition device 100, wherein the iris camera module 10 can collect one eye user iris characteristics or binoculus user iris characteristics. The fill light component 20 provides additional fill light resource for the collected iris region.

In other words, the using of the binoculus iris images data acquisition module 600 does not affect the physical and mental health of users.

It is also worth mentioning that the fill light component 20 is preferably an infrared LED light emitting element to ensure that the energy consumption of the fill light component 20 is reduced under the condition of the fill light component 20 being able to provide enough additional infrared light for the binoculus iris images data acquisition module 600.

In some embodiments of the present invention, the iris camera module 10 is preferably an infrared camera module, so that when the iris camera module 10 collects the user binoculus iris characteristics, the adverse effects of visible light to the image quality is reduced and a better image effect is obtained.

Specifically, the lens assembly 112 of the iris camera module 10 further comprises a lens 1121, a lens holder 1122, an infrared carrier penetration filter 1123 and other components. The lens holder 1122 is mounted on the printed circuit board assembly 113. The lens 1121 and the infrared carrier penetration filter 1123 are supported by the lens holder 1122. Wherein when the iris camera module 10 shoots the objects, the reflective light of the object successively passes through the lens 1121 and the infrared carrier penetration filter 1123, and then images in the image sensor chip 111, so that an electrical signal is converted in the image sensor chip 111.

It is worth mentioning that the infrared carrier penetration filter 1123 filters out the visible light which through the lens 1121 and only allows infrared lights to cross through. In other words, the lights passing through the lens 1121 and received by the image sensor chip 111 is infrared light which carries the user iris characteristics, so that the interference of the visible light to the user iris image collected by the iris camera module 10 is avoided as much as possible.

As shown in FIG. 5 of the drawings, the horizontal field angle of the iris camera module 10 is defined as the length direction of the user binoculus and the vertical field angle of the iris camera module 10 is defined as the width direction of the user binoculus. When choosing and providing the angle between the fill light component 20 and the iris camera module 10, in order to ensure that the generated light of the fill light component 20 can cover the region which the iris camera module 10 covers, the light emitting angle of the fill light component 20 is respectively greater than the horizontal field angle and the vertical field angle of the iris camera module 10. In this way, it can make the coverage range of the fill light component 20 to be greater than the coverage range of the iris camera module 10 in the same projection range.

In detail, during the process of collecting the user iris characteristics of the binoculus iris images data acquisition module 600, the iris camera module 10 covering the face region of the user is defined as an interior region, so that when the iris camera module 10 collects the user iris characteristics, the focal point can be located inside or close to the user iris region. More preferably, the focal point is located in the user's pupil region.

It is worth mentioning that the area of the interior region is relative to the horizontal and the vertical field angle of the iris camera module 10.

Accordingly, the fill light component 20 covering outside of the user's face region is defined as an exterior region. As the light emission angle of the fill light component 20 is respectively greater than the horizontal and the vertical field angle of the iris camera module 10, so that the user face region covered by the fill light component 20 is always comprises the user face region covered by the iris camera module 10 and at least one eye of the user is located in the interior region. In such a manner that the fill light component 20 provides additional infrared light source for the iris camera module 10 in any cases.

It is understandable that the light emitting element 21 of the fill light component 20 has a light emitting angle which is set to be less than 90 degrees, so that the supplemental infrared light source provided by the fill light component 20 is effectively utilized. It is worth mentioning that when the light emitting angle of the fill light component 20 is set to be 0-45 degree after repeated detection, the fill light component 20 and the iris camera module 10 has a better configuration effort. Moreover, under the condition of ensuring that enough supplementary infrared light is provided for the binoculus iris images data acquisition module 600 by the fill light component 20, the energy depletion of the fill light component 20 is reduced.

As shown in FIG. 7 of the drawings, a distance between the iris camera module 10 and the user iris is defined as z, an axle distance of the iris camera module 10 and the fill light component 20 is defined as x. A preset angle of the fill light component 20 is defined as θ. The value of x can be determined by adjusting the value of θ. In this way, the deviation value of the iris camera module 10 and the fill light component 20 can be determined, so that the user binoculus region covered by the fill light component 20 of the completed binoculus iris images data acquisition module 600 is always comprises the user binoculus region covered by the iris camera module 10, thereby ensuring a stability and reliability during using of the binoculus iris images data acquisition module 600.

It is worth mentioning that, when the angle θ is reasonable, the reflective spots formed on the user iris is reduced or is far away from the user iris region when the iris camera module 10 collects the user binoculus iris characteristics. For example, under the effect of the fill light component 20, the reflective spots is generated in the user sclera region or other positions, so that the generated reflective spot having interference on the image quality is reduced when the iris camera module 10 collects the user binoculus iris characteristics.

As shown in FIG. 36 of the drawings, the reflective spot does not affect the image quality of the user binoculus iris characteristics collected by the iris camera module 10, so that the iris camera module 10 can be more accurately to capture the user iris characteristics. Thus, in some embodiments of the present invention, the reasonable angle θ range is 0 degree to 45 degree.

Those skilled in the art will understand that when the light emission intensity of the fill light component 20 cannot meet the brightness of the requirement of the iris camera module 10 collecting user iris characteristics, on one hand the brightness of the fill light component 20 is increased and on the other hand the iris recognition device 100 can be provided with two or more than two fill light component 20.

It is worth mentioning that, under the condition of providing a plurality of the fill light component 20, each of the fill light component 20 is uniformly arranged around the iris camera module 10, and while the angle and deviation value of each of the fill light component 20 and the iris camera module 10 are adjusted, so that the binoculus iris images data acquisition module 600 has a higher accuracy on iris recognition and user authentication.

It is also worth mentioning that the image quality of the user iris characteristics iris collected by the iris camera module 10 has an important influence on the computing speed and the logic complexity of the iris recognition device 100, and has an impact on the recognition range of the iris recognition device 100. Those skilled in the art will understand that when image quality of the user iris characteristics iris collected by the iris camera module 10 is high, the complexity of the logic design of the iris recognition device 100 can be reduced, so that the consumed time of the iris recognition device 100 on user authentication is shortened.

Those skilled in the art will understand that the iris camera module 10 can be achieved the long-distance user to iris recognition by rational design. In the preferred embodiment of the present invention, the iris camera module 10 enables a long-distance user iris recognition, by the miniaturization of the pixel size of the image sensor and the quantifiable selector mode of the crosswise pixel quantity, and combining with the design value of the len hfov to extend the recognition distance of the iris camera module 10, thereby improving the practical value of the binoculus iris images data acquisition module 600.

It is worth mentioning that, compared to traditional iris recognition technology, the binoculus iris images data acquisition module 600 can not only be used to collect the user binoculus iris characteristics, but also to collect user monocular iris characteristics, and in the actual application process, the binoculus iris images data acquisition module 600 shows a good performance.

In other words, in the range of f, the number of pixels needs not less than f*N, and the corresponding image size of the image sensor chip 111 is f*N*D. According to the principle of similar triangles, the proportional relation is as follows: (f*N*D)/f=a/(c−a); under the condition of the known N, D, c, the focal length a of the iris camera module 10 is a=c*D*N/(D*N+1) after being calculated.

The number of the horizontal maximum output pixels X of the image sensor chip 111 based on the principle of similar triangles is: X*D/e=a/(c−a); and the horizontal maximum shooting range in the farthest distance e after being calculated is: e=X*D*(c−a)/a.

Meanwhile, according to the principle of similar triangles: (b−a)/a=f/(X*D); the closest distance of the user binoculus iris recognition b after being calculated is: b=[f/(X*D)+1]*a.

Meanwhile, according to the principle of the triangle function: tan (β/2)=(e/2)/(c−a), the horizontal field angle β of the iris camera module 10 after being calculated is: β=2*arc tan [(e/2)/(c−a).

In the preferred embodiment of the present invention, based on the calculated relationship, the relative dimensions of the binoculus iris images data acquisition module 600 are obtained.

The first lens 1000, the second lens 2000 and the third lens 3000 are sequentially arranged from the object side of the camera optics lens assembly to the image side of the camera optics lens assembly (as shown in FIG. 39 of the drawings from left to right) to form the camera optics lens assembly, and simultaneously to form an optical axis through the middle of the first lens 1000, the second lens 2000 and the third lens 3000, the camera optics lens assembly further comprises an aperture slot, which is located between a shot object and the second lens 2000. And in the follow-up, the camera optics lens assembly is used to cooperate with an image sensor chip 111 to form the iris camera module, wherein the image sensor chip 111 has an imaging surface 1111 toward the camera optics lens assembly for optical-electrical conversion in the image sensor chip 111.

It is worth mentioning that the aperture slot can be a diaphragm, a field aperture slot, etc., which is selectively disposed at the position between the shot object and the first lens 1000 or is disposed at the position between the first lens 1000 and the second lens 2000 for improving image quality of the shot object imaging on the imaging surface 1111.

It is worth mentioning that the convex curvature of the first lens object side surface 1200 can affect the value of the field angle of the camera optics lens assembly. In other words, the field angle of the camera optics lens assembly can be increased by adjusting the convex curvature of the first lens object side surface 1200. Moreover, in this embodiment of the invention, the first lens object side surface 1200 is designed to be unsmooth, in particular, the periphery of the first lens object side surface 1200 forms a convex curvature which is different with the middle of the first lens object side surface 1200 thereof so as to modify the distorting discrepancy resulting from the increasing of the field angle of the camera optics lens assembly, thereby avoiding image distortion of the user iris characteristics collected by the camera optics lens assembly.

Furthermore, the convex design of the first lens object side surface 1200 further enhances the positive refractive power of the first lens 1000 in order to further reduce overall length of the camera optics lens assembly based on ensuring that the camera optics lens assembly having a larger field angle, so that the size of the camera optics lens assembly is smaller so as to be integrated in the follow-on devices such as the electronic devices.

The second lens 2000 is a lens having a negative focal power to provide a negative refractive power, and to modify the discrepancy resulting from the excessive positive refractive power of the first lens 1000. The second lens 2000 has a second lens imaging side surface 2100 and a second lens object side surface 2200. The second lens imaging side surface 2100 towards the imaging surface 1111 and the second lens object side surface 2200 towards the first lens imaging side surface 1100. The second lens object side surface 2200 is a concave surface so as to modify the Petzval sum of the camera optical lens assembly, so that the middle and the periphery of the second lens 2000 both have a good imaging performance to ensure that the iris cameral module manufactured by the camera optics lens assembly has a reliability and stability during using process.

It is worth mentioning that in some embodiments of the present invention, according to the lens curvature radius, the second lens imaging side surface 2100 is a convex surface. While based on the vector height of the lens, the second lens imaging side surface 2100 can be a convex or concave surface, so that the camera optics lens assembly has different operational performances.

The third lens 3000 is a lens having a negative focal power to provide a negative refractive power, wherein the third lens 3000 has a third lens imaging side surface 3100 and a third lens object side surface 3200. The third lens imaging side surface 3100 towards the imaging surface 1111 and the third lens object side surface 3200 towards the second lens imaging side surface 2100. The third lens object side surface 3200 is a concave surface.

It is worth mentioning that in some embodiments of the present invention, the third lens imaging side surface 3100 is a convex surface.

In this embodiment of the present invention, at least one side of the first lens imaging side surface 1100, the first lens object side surface 1200, the second lens imaging side surface 2100, the second lens object side surface 2200, the third lens imaging side surface 3100 and the third lens object side surface 3200 is aspherical so to meet the needs of the camera optics lens assembly manufacturing the iris camera module.

It is worth mentioning that in some embodiments of the present invention, every sides of the first lens 1000, the second lens 2000 and the third lens 3000 can be aspherical such that the camera optics lens assembly is configured with parameters by designing the first lens 1000, the second lens 2000 and the third lens 3000 into different shapes, thereby eliminating imaging aberration as much as possible.

Moreover, the material of the first lens 1000, the second lens 2000 and the third lens 3000 can be selectively from plastic or glass. For example, when the first lens 1000, the second lens 2000 and the external system 300 are made of plastic material, the camera optics lens assembly has a lower manufacture cost and the manufacturing difficulty is reduced to further improve the product yields; when the first lens 1000, the second lens 2000 and the external system 300 are made of glass material, the configuration freedom of the refractive power of the camera optics lens assembly can be increased so that when the camera optics lens assembly is manufactured into the iris camera module, the image quality of the collected user iris characteristics is improved.

After the camera optics lens assembly is configured, the spatial position is stable. In other words, the spatial positions of the first lens 1000, the second lens 2000 and the third lens 3000 become stabilized, and the first lens 1000, the second lens 2000 and the third lens 3000 have a certain gap in order to prevent the collision among themselves during the assembly of the camera optics lens assembly and so as to improve the information content of the collected user iris characteristics by the iris camera module by enhancing the sharpness of the user iris characteristics image collected by the iris camera module manufactured from the camera optics lens assembly.
